Modular ceiling accessible one by one, hidden grid, resting on all four sides, allowing for reduced thickness and larger formats

ABSTRACT

The present invention discloses a rectangular ceiling module, accessible one by one, that allows the use of larger-than-standard, reduced-thickness formats, with a front face, a rear face and four edges, with corners forming obtuse angles and robust geometry; it is installed from below without surpassing the height of the standard support grid; it rests on the grid by its four edges or sides and leaves the grid hidden. The module is useful as a standard false ceiling, hiding air-conditioning installations, electrical installations, fire-protection systems, low-current systems, etc., located under the slab, mostly in office buildings, while also serving as an element of insulation and/or sound absorption, depending on the material used.

State of the Art In the world of construction, where the plenum is used,separation between a false ceiling and the slab, to carry the facilitiesof all the services that the place has such as electricity, firesystems, air conditioning systems , weak currents, etc., the removablemodular ceiling is commonly used to give a flat termination to it and tohave access to this equipment. For its installation, a standard profileis used that hangs from the slab, and is known as 15/16 profiles, ininches, or 24 mm profiles in metric system. A 61×61 cm or 61×122 cm gridis assembled on which the modular ceiling is installed, leaving theprofiles visible. As an evolution of a better aesthetic presentation,the low-edged ceiling modules were developed, where the module, as itsname indicates, has a recess in its four support edges, which allow thepalmette or module to lower more than the profile, taking away theaesthetic prominence from the profile. An even better aestheticalternative is that of the modules that hide the profiles, which is towhich the present invention belongs, where the dimensions of the face ofthese modules is greater than the space left by the support grid. Astandard 15/16 grid (24 mm face), composed of 366 cm principals and 122cm and 61 cm secondaries, leaves a clearance between profile edges of586×586 mm or 586×1.196 mm (610-24=586 mm or 1,220-24=1,196 mm).Depending on the solution used, they hide the grid, leaving a stoneworkbetween the modules that ranges from 1 mm to 6 mm, depending on thechosen system. The smaller the quarry, the smoother the modular ceilingis perceived as a whole.

In the market for accessible modular ceilings that hide the supportprofiles and leaving a stonework in sight, there are severalalternatives that have the characteristic that they are supported on twosides, requiring attached elements such as hooks, folded cans, etc. thatact as a retention or safety element when the sky module, due to amanipulation movement or a telluric movement, has released one of itssupports, so the module falls to the ground (examples, Natura de HunterDouglas or Armstrong Vector).

By leaning on two sides, it also has the limitation that the distancebetween the two support points is limited, since since the force ofgravity acts in flexion on these modules, it causes them to deform dueto its action. To avoid deformation, these types of ceilings are forcedto have a maximum width format (between the two supported edges) of 61cm and a material thickness of 16 mm for agglomerates and 18 mm formineral fiber.

A better solution to the previously described alternatives of ceilingswith hidden profile is the Chilean patent 200500058 Recordable SkyModule and patents US20060162283 and EP1690994.

The fundamental characteristic of this solution is that it is supportedon its four sides, where its installation is carried out using recesseson the shorter sides of the module, which cut the geometry of the edge,maintaining continuity only on the face, in order to install it. . Thisdesign is currently on the market and uses 12 mm medium densityfibropanel as a substrate, (mdf=medium density fiber panel) that doesnot deform because it rests on all four sides, which works withoutproblems since its density is The right one for the design of the edges,their resistance and the dimensions of the modules, which cannot exceed61 cm on the shorter sides, where the installation recesses go. If youwanted to make a ceiling module with a width of 122 cm, you would haveto increase the length of the outlet or installation recess (Figuren° 1) to such a degree that it jeopardizes the effectiveness of theanti-seismic condition, as the removed so significant (90 cm from 122cm) and leaving 90 cm of the removed as the deformation distance of themdf board product of gravity, which would imply the need to use agreater thickness, therefore a greater weight. 69 Therefore, the realrange where this design can be used is, at most, a medium densityfibropanel ceiling module of 12 mm of 61×122 cm and in the case oflow-density materials, given the fragility of the shape of their edges,it can be used only in places where there is no need for registrabilitybut for the acoustic capabilities of the mineral fiber module. Theceiling module of the invention allows its dimensions to be increasedwithout losing its safety characteristics, not deforming and alsoreducing the weight per square meter by requiring a smaller thickness,which for MDF can be 9 mm and for mineral fiber 12 mm or 15 mm, thelatter depending on the density of the material. In the case of lowerdensity materials such as mineral fiber, they can be used in all places,regardless of the degree of their need for registrability.

DETAILED DESCRIPTION OF THE INVENTION

The technical problem that the new hidden profile recordable ceilingmodule solves is that it allows the use of low-density materials withoutregistrability limitations, in formats greater than the standards and inthicknesses less than 12 mm, without losing anti-seismic safetycharacteristics and without deforming.

It does not differentiate between widths and lengths, since its fouredges have the same design at the corners. 91 For materials such as MDFor medium density fibropanel and others like it, it allows the use of 9mm thicknesses, which implies a significant reduction in the finalweight.

The invention is a rectangular module with a face (c) that is visiblefrom below and that is the one with the greatest dimension, four edges(3), each one composed of the recesses (3 a), (3 b), (3 c) and (3 d),and a back (d) with a dimension greater than the distance between theedges of the support profiles.

Generally this larger dimension is 5 mm more on each side and that is bymeans of which it is supported (3 d). This support profile (3 d) has atleast two recessed corners, the one that goes from (1) to (2),increasing the angle of these corners, being the optimum to use the fourequal corners. Considering a 610×610 mm module, these recessed cornersgo from a right angle to an obtuse angle of 94° and where the length ofthe recess is 10 cm, distance from (1) to (2), the same length as therecess of (1 b) to (2 b) corresponding to edge 3 b and which is parallelto the recess of edge 3 d. The length of both recesses must be the sameand may vary, depending on the format of the ceiling module.

Invention corners makes installation much more intuitive,

simple and in fewer steps.

The angle of the corners increases from 90° to 94° by lowering the uppersupport flange (3 d) 3 mm thick and 5 mm deep (1), from a distance of 10cm, to 0 mm deep (2). The recess describes a diagonal from 10 cm fromthe corner (1), where the flange has a depth of 5 mm, to the corner

itself (2), where its depth decreases until it reaches 0 mm. In thecorner (2) its thickness (3 d) is added to the thickness of the secondslot (3 c), resulting in a support rectangle 7 mm thick and 6 mm deep,much more robust. The new ceiling design, in addition to the above,“hides the profiles, it is installed from below without exceeding the

height of the support profiles, it can be registered one by one,individually, without difficulty or deterioration and is anti-seismic asit is supported on its four sides”.

The length of the corner recess makes sense from 1 cm to 15 cm.

If the length of the module is 122 cm, 15 cm is justified so that itsend does not

it is so far from the profile, for a 61 cm side, a 10 cm recess issufficient.

TO!

increase the dimensions of the module from 61×61 cm to 122×122 cm, thedesign of the corners remains unaltered, maintaining the security of itsfixation, the simplicity of the installation, using the same standardprofiles and

also without the need to increase its thickness.

The edges (3) of the module are made up of the recesses (3 a), (3 b), (3c) and (3 d), which have as a restriction that, in order to be able touse separation edges of the modules of 0.5 mm or more, its registrationcan be done one by one, simply and independently from the rest of thesky modules.

This

It is achieved by making the rectangle of the ceiling face (3 a) have athickness less than the sum of the rectangles in the middle of themodule, (3 b)+(3 c), plus the thickness of the fixing profile, which is1 mm.

The conditions that each of these rectangles that make up the edges mustmeet are:

as 3rd.—visible face and edge: it must have a maximum thickness thatallows entering the handling space left by rectangles two and threeminus the thickness of the profile, which in the case of mdf should be2×17 mm and for mineral fiber 15 mm should be 5×17 mm.

3 b.—handling space: it must be high enough to be able to

manipulate the profile inside while the installation is being carriedout, which for MDF Gaso should be 2 mm and for 15 mm mineral fiber itshould be 3 mm. 3 c.—spacer between profile edges: it must have athickness that allows the module to easily find its position containedbetween the edges of the profile, which in the case of MDF should be 3×6mm and for mineral fiber 5 mm it should be 4×6 mm.

3 d,—support on the profile; It must be solid enough to support theweight of the module, which for the 9 mm mdf case should be 2×5 mm andfor the 15 mm mineral fiber it should be 3×5 mm.

The support of the modules is carried out by means of a continuousprofile with an inverted T shape, which is hung from the earthenware bymeans of wires or profiles designed for this function.

They are hung at a distance of 1220 mm one from the other, separated bya profile module of the same inverted T design, with which a mesh of1220×1220 mm rectangles is assembled between axes, 1220×1220 mm grid.

If, parallel to the main profiles, another 1220 mm secondary profile isinstalled between the two 1220 mm secondary profiles, a grid of 1220×610mm rectangles is formed.

If these rectangles in turn are subdivided by means of a secondary of610 mm between the main profile and the secondary parallel to this of1220 mm, which is located between the main ones, squares of 610×610mmare formed, grid of 610×610 mm.

All these grids are also supported by an angle-shaped profile thatsurrounds the entire perimeter, is fixed to the wall that contains themodular ceiling space and is called the perimeter profile.

The width of the profile in its visible or lower part is 24 mm ( 15/16inches).

The fixing profiles are made of galvanized and enameled steelapproximately 0.8 mm thick,

The four corners (2) of the recordable ceiling module of the inventionallow the installation to be carried out from a turning movement withdisplacement plus a straight diagonal adjustment.

The Recordable Sky Installation and Removal Procedures are part of thepatent being applied for.

Installation is carried out by inserting the profile into the recess (3b) in the corner (2 a) of the module, until it touches the vertical wallof the profile.

This corner (2 a) is moved parallel to its profile towards the corner ofthe grid (5), taking care that when the corner (2 b) moves, the gridenters the slot (3 b) of the module until it touches the vertical wallof the profile.

With both corners, (2 a) and (2 b), touching the profiles on theirvertical wall, the corner (2 a) of the module is moved to the corner (5)of the profile, producing a rotation of the module that will carry thecorner (2 b) of the module to the corner (6) of the grid.

In that position the lengths (7) and (8) of the module are supportedagainst the respective profiles, so that the opposite lengths of themodule are free from the profile at the level of the back, so thiscorner is raised over the profile level.

Once this has been achieved, the module is moved diagonally in thedirection of the corner (9), managing to locate the ceiling in the finalposition, where the module goes down, remaining completely supported onthe back flange (3 d) and leaving the four lengths at the same distancefrom the grid.

The module uninstallation procedure consists of carrying out the reverseprocess, that is, the module is lifted leaving the rear face of the facerecess (3 a) touching against the profile, the module is moveddiagonally towards the corner of the profile (5), up to their maximumposition, that is, the lengths (7) and (8) remain touching the profiles,at which point the opposite corner (9) is free to lower the level withrespect to the profiles, move the corner to the side that is touchingthe profile (2 a) parallel to the corresponding profile at the same timethat the front corner (2 b) also moves parallel to its respectiveprofile, that is, two straight movements in a perpendicular directionproduce rotation and translation which finally leaves the ceiling modulefree, the module being removed when it is rotated about 20 degrees withrespect to the grid.

If we consider a ceiling module formed only by the back (d) and thethird recess or adjustment (3 c), which is the one that is containedbetween the edges of the grid profiles, we have a Ganto recordableceiling module recessed, where the spacing recess (3 c) has a thicknessof 9 mm, the distance from point (1) to (2) corresponds to the recess ofthe support flange (3 d) and that for this case does not reach 0 mm inthe corner, but at 2 mm (4), so that it cannot be seen from below, upthe corner.

That is, it can be up to 0 mm as well, but it is not the most aesthetic.

The installation and removal method are the same as those of the moduleof the invention, considering that when the profile is inserted into thelargest recess (3 b) for the main design of the invention, in this casethe new face of the module (c1) will be on the wing of the profile.

If we add a rectangle 5 mm thick by 25 mm long (11) to one of its edgesof the face (c1), if we add a rectangle of 5 mm thick by 25 mm long(11), with a spacing recess of 9 mm, we have a Lowered ganto that in oneof the edges is a hidden profile.

This module can be defined as a hidden corridor profile ceiling module,where one is installed one after the other, covering the separationprofile, leaving the last one only as a traditional lowered edge, sothat the same lowered edge termination remains throughout. the perimeterof the installed “corridor ceiling”, which is a lowered edge and whichis a hidden profile in all the separations between modules.

Increasing the format of the recordable ceiling module of this inventionis very simple since the corners remain unchanged and only the lengthbetween them is the one that increases its dimension, the one thatmaintains its support throughout the length to be increased.

This, in the case of the state of the art CL200500058, is not the casesince by increasing the width format, which is the one with theinstallation recess, the recessed section must be lengthened, sinceotherwise it cannot be installed.

This means that if we lengthen the width up to 120 cm, so that theinstallation recess can work, this will be the one that must increaseits length, so the support section (e) to (f) will remain unchanged.This makes the support area of these sides decrease from 50% to 25%,that is, the recess will be 91.5 cm from the 122 cm long, which will notbe supported or adjusted by the profiles, which It implies a lowerdegree of security against manipulation and earthquakes, that is, itsanti-seismic quality will be lost. In addition, having the module 91.5cm unsupported, with a length of 122 cm, it will be affected by thedeformation caused by the force of gravity, which would lead to increaseits thickness, and therefore its weight, in order to make up for it.
